In the same area as the renowned "Vucciria" Market, this church represents one of the highest expressions of the Baroque stile in Sicily. The current construction was finished around the end of the 17th Century and is the third version of the church built by the Domenican monks who came to Palermo around 1217. Its facade was added in 1726, two years after the new piazza (square) was opened. The plasticity of the severe and dominating Baroque tone of Palermo churches is mitigated here with a style that is more airy and spacious. The inside is in the form of a Latin cross with three naves and deep chapels embellished with columns and arches.
